CURTAIN BOD.

Application filed July 29, 1926. Serial No. 185,770.

it in curtain suspending position without the employment of supporting brackets for the rod, or hold fast devices, such as screws, rivets, bolts or nails.

A further object ofthe invention is to provide, in a manner as hereinafter set forth, a curtain rod including a pair of adjustable, spring-controlled, telescopic sections and means common to said sections for increasing or decreasing the tension of the controlling spring for such sections when occasion requires, and further with each of said sections provided at the outer end thereof with a suction cup acting to fixedly secure or retain the rod in curtain-suspending position.

Further objects of the invention are to provide, in a manner as hereinafter set forth, a curtain rod, Which is simple in its construction and arrangement, strong, durable, compact, adjustable, thoroughly efficient in its use, conveniently secured in curtain suspending position, readily assembled, and comparatively inexpensive to manufacture.

with the foregoing and other objects in view, the invention consists of the novel construction, combination and arrangement of parts, as hereinafter more specifically described and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which fall within the scope of the claims hereunto appended.

In the drawings wherein like reference characters denote corresponding parts throughout the several views:

Figure 1 is a longitudinal sectional View of a curtain rod, in accordance with this invention, illustrating the same assembled and in curtain-suspending position.

Figure 2 is a perspective View of one of the tensioning rods for the controlling spring for the sections of the rod body and said rod is of greater length than the rod shown in Figure 1.

Figure 3 is an end view of the curtain rod. 1 1

Figure 4 is a section on line 44,' Figure 1. a

Figure 5.is a section on line 5-5 Figure 1.

A curtain rod, in accordance with this invention comprises a sectional telescopic body portion, a pressure exertin spring mounted in one of the sections of an further common to all of the sections of the body portion, a plurality of spring-tensioning rods each common to the sections of the body portion and co-acting with the pressure exerting spring for limiting the expansion thereof to maintain the sections of the body portion in adjusted position, and a suction cup carried by each section of the body-portion and with the cups providing means for fixedly securing or retaining the body portion in curtainsuspending position after the body portion has been adjusted to the desired length.

The body portion of the rod is formed of a pair of tubular sections 1, 2 and with the former of less diameter than and extending into the latter. The sections 1 and 2 can be constructed of any suitable material, but preferably metal and each of said sections is open at each end. The diameter of said sections can be any diameter desired, but the diameter of the section 1 must be less than that of the section 2 and of such diameter as to snugly engage the inner face of the section 2 to provide a sliding fit between the sections.

Secured to the outer end of the section 1, as well as to the outer end of the section 2, is a suction cup, and as each of said cups is of the same construction, but one will be described as the description of one will apply to the other. Each cup comprises a body portion 3 of resilient material having a concavity 4 in its outer face. Extending inwardly from the body portion 3, as well as axially thereof, is a sleeve 4 which provides in connection with the body portion a socket 6. The base of the socket 6 closes the outer end of a tubular section of the body portion. The outer terminal portion of each tubular section is extended into a socket 6 and owing to the resiliency of elasticity of the material from which the cup is formed, the cup tightly engages with a section whereby the cup and section are secured together.

The pressure exerting spring is indicated at 7, and is of the coiled type. Said spring 7 is mounted in the section 1 of the body portion and is of less length than the length of the latter. One end of the spring 7 abuts against the base of that socket 6 into which extends the outer end terminal portion of the section 1.

The rod further includes a plurality of spring tensioning rods of different lengths, and although the drawing shows but two of these rods, vet the number thereof can be increased. ne of the rods is indicated at 8 and the other at 9. The rod 8 is of greater length than the rod 9. The diameter of each of the rods is substantially the same as the inner diameter of the section 7, but the diameter of each of the rods is materially less than the inner diameter of the section 2. Ea h rod when mounted in position to limit the expansion of the spring is positioned in the section 1 and also in the section 2.. and abuts against the base of that socket 6 into which extends the outer terminal portion of the section 2. The diameter of each of the rods is such as to pro vide a sliding fit between the periphery thereof and the inner face of the section 1 of the body portion of the rod. If an i elongated rod is mounted in the sections of the body portion, the tension of the spring 7 is greater than if a shorter rod is mounted therein. Each rod coacts with the spring 7 for the purpose of maintaining the sections 1 and 2 in adjusted position and with the cups 3 or rather body portion of the cups held tightl against a pair of abutments or opposed sic es of a window frame. The suction action set up by the cups being such as to fixedly secure or retain the rod in curtain supporting position.

Each of the rods preferably is constructed of wood, but it is obvious that each rod can be of any other suitable material. When the curtain rod is set up if it is found that the spring 7, does not exert sufficient pressure to provide for the gripping of the suction cups, then the spring tensioning rod is removed from the section of the body portion and one of greater length substituted,

, under such conditions increasing the tension of the spring 7 so as to provide for the gripping action of the suction cup to fixedly secure the curtain rod in curtain suspending position.

It is thought the many advantages of a curtain rod, in accordance with this invention, can be readily understood, and although the preferred embodiment of the invention is as illustrated and described, yet it is to be understood that changes in thedetails of construction can be ,had which will fall within the scope of the invention as claimed.

What I claim is:

1. A curtain rod comprising a pair of tubular sections, one having its inner end extending into the inner end of the other, each of said sections of uniform diameter throughout, said sections open at each end, a retaining element for each of said sections, each retaining element mounted on and projecting from the outer end terminal portion of that section with which it is associated, a pressure exerting spring loosely mounted in the section of smaller diameter and bearing against one of said elements intermediate the ends thereof, and a plurality of spring tensioning rods of different lengths, each having the periphery thereof plane throughout, said rods selectively mounted in both of said sections, bearing against the other of said elements and against said spring for limiting the expansion of the latter.

2. A curtain rod comprising a pair of tubular sections, the inner end of one section extending into the inner end of the other section, each of said sections of uniform inner diameter throughout, a pair of opposite- 1y disposed suction cups, each having the outer side thereof formed with a socket, each of said cups mounted on and projecting from the end terminal portion of a tubular section and providing a retaining means therefor, a pressure exerting spring loosely mounted in the tubular section of smaller diameter and bearing against one of said cups at the base of the socket in the latter, and a plurality of spring tensioning rods of different lengths selectively mounted in both of said sections, bearing against the base of the socket in the other of said cups and against said spring for limiting the expansion of the latter and to maintain said cups in gripping engagement with a support to retain the curtain rod in curtain suspending position, each of said rods having its periphery plane throughout.

In testimony whereof, I afiix my signature hereto.

GEORGE A. BOOTH.
